The only thing I can remember is a verse from the song and that it is a female singer. The part I remember is : "its only your shadow on the wall". I know its very little to go on.

Is it this?

Artist: Britney Spears Lyrics
Song: Shadow Lyrics

Your body's warm
But you are not
You give a little
Not a lot
You coup your love
Until we kiss
You're all I want
But not like this
I'm watching you disappear
But you, you were never here

It's only your shadow
Never yourself
It's only your shadow
Nobody else
It's only your shadow
Filling the room
Arriving too late
And leaving too soon
And leaving too soon

Your body gives
But then holds back
The sun is bright
The sky is black
Can only be another sign
I cannot keep what isn't mine
You left and it lingers on
But you, you were almost gone

It's only your shadow
Never yourself
It's only your shadow
Nobody else
It's only your shadow
Filling the room
Arriving too late
And leaving too soon
And leaving too soon

I cannot tell if you mean what you say
You say it so loud, but you sound far away
Maybe I had just a glimpse of your soul
Or was that your shadow I saw on the wall
I'm watching you disappear
But you, you were never here

It's only your shadow
Never yourself
It's only your shadow
Nobody else
It's only your shadow
Filling the room
Arriving too late
No, no, no
It's only your shadow
It's only your shadow
Nobody else
It's only your shadow
Arriving too late
And leaving too soon

It's only your shadow

Thank you!! It was driving me crazy.
